Testing apps in Foldables

Testing App continuity

App developers can now test how their apps respond in a foldable environment. This enables them to verify that it was done correctly by using an emulation environment that is provided for app continuity and multi-resume.

Prepare Foldable Devices

The emulator app, which can run on Android devices and Android Studio AVD, is provided to test for changing screen size and density. It's recommended to use any Android tablets such as Nexus10 that can contain screen size which is not smaller than main display screen size(1536 x 2152). That's because the devices that have smaller screen size than main display can not emulate the same condition, which can make different layout in your devices.

However, if you don't have recommended devices, you can test your app in the emulator, and you can check whether your app works well when screen size changes. Additionally, you can test your app without a real device, There is an Android Virtual Device in Android Studio, but it's very difficult to use equipments such as SIM, wifi, camera and so on if you uses AVD.
